In the course of preparing a Master Plan and Environmental Impact Statement for Cape Disappointment State park in Washington, GreenWorks also prepared an extensive Cultural Landscape Report for the Park. Extensive historical research and on-site archeological investigations were conducted by a sub-consulting firm. This background material, combined with interviews and historical documents, served as the foundation for the Cultural Landscape Report for this 1800 acre State Park. We coordinated our efforts with the Historic Preservation Officer from both Washington State Parks and the State of Washington. Because of the unique qualities of Cape Disappointment, including a visit by the Lewis and Clark Corps of Discovery, historic coastal fortifications from three US wars, two historic lighthouses, considerable historical use of the site by Native Americans, and the site’s physical transformation as a result of jetty construction, GreenWorks also involved the National Park Service in reviewing the methodology and findings.
